I believe thats what its called. When I installed the s/c, I had no idea what to do with the pcv hose, so I put a breather filter on it. I have noticed recently it is smoking a tad out of the breather filter, and smells like fuel. Any ideas?
Buy a catch can, you will soon notice oil coming out of the filter under high boost and it makes a mess.
well if it is any thing like the 2.4L GM s/c'er kit there should have been a hose that connects back into your intake track before the throttle body

The S/C doesn't route it back into the intake at all? You want a hose that goes to a catch can, then another hose on the other end to route the emissions back into your engine. If the s/c doesn't have a connection for it, then you can thread a hole into your intake tube and run it there. Otherwise, put the breather filter on the other end, but in most places those are illegal.

Poor mans catch can That's what I used for mine and routed back into the intake to appease the Smog Nazi's.
dammit. Go to www.homedepot.com and search for part# HDA70400AV
I broke the stone filter off.

Yep I have the same setup and it works great and passes inspection plus you have the ability to easily discard the oil

Well if you plug it, it won't breathe. I'm not sure if it's going to cause a problem plugged. You may want to leave it unplugged, just not routed to anything.
definently do not plug the engines ability to breath. If you do that you run the chance of the escaped gasses in the crankcase to actually ignite not to mention your oil will quickly become VERY polluted with carbon and everything else. Plug it if you wish but it = bad stuff

Ahhh ok,, thanks guys.. Ill leave it open then..
Also, I just bought this catch can, 1/4 npt fitting to 3/8 barb, and 3/8 hose.. I now am realizing that on the 2.4 crankcase breather outlet is WAY bigger than 3/8 hose lol... Do you you guys have Idea on how I could connect the two?

what ever u do don't hook it up to your intake u don't want to suck that junk into the motor you will line the inside of your intake blower and head with oil and that leads to carbon in the combustion chamber and carbon makes the computer pull timing not counting what that does to the ring lands and cylinder walls just put a breather on it and a catch if needed
thanks guys, I actually went and looked at the instructions again, and realized that was the only thing we didnt check off on the list. I put the hose from the cover to the intake, like it said. Would I be alot better off just running a catch can? Or is the stock setup fine?

The engine is meant to burn off those emissions. Dumbass.

unless its a emissin law there or somthing do not do it put a breather / catch can on its the best thing u could do there is no negative as far as the motor is conserned u will only gain power and make your blower and engine last much longer.
GM's instructions say to route the breather into the intake. Adding a catch can, or the poor mans catch, helps keep the intake track cleaner.
Actually the best thing IS to hook it to the intake. If you just have it venting to atmosphere the gases only escape (for the most part) at their own leisure. The intake is used to help EXTRACT the gases before build up and then to re-burn the gasses lowering emissions and evacuating your crankcase to keep the oil clean and pretty. Regardless if your in a state that requires the crankcase ventilation system to be all in order, its the best route to protect your engine anyway. The carbon buildup is relatively non existent when a catch is utilized but it should be routed after the catch back to the intake stream

Thanks for all the info. I will stick with it just routing to the intake for now, then maybe do a catch can later on, as nebraska has no emissions.

Holy crap.
Yeah guys no need to worry about Positive Crankcase VENTILATION! ... Just plug it off , you'll be fine! /Sarcasm and idiot speak.

I'd just stick with keeping it hooked up to your intake, you'll get better gas mileage (granted you may not care, but theres no point in wasting whats ventilated).

are u guys for real for one it won't give u better mileage,power, or longevity so were nice clean air and fuel could go u have took its place with a slurry on oil fumes and blow by (exhaust) something that will NOT combuste again and only impares the explosion and in no way is the motor designed to burn the emissions "dumbass" the only reason gm pipes it in is because its the easiest and most cost affective way to deal with it and buy the time u start to suffer the side affects its your problem because warranty is long gone and in no way does it clean your oil i don't know were u were going with that and yes the gases are suppose to leave at there leaser thats why there is a oil separator on the front of the motor instead of a "positive crank ventilation system" aka vacuum line hooked directly to the manifold with a check valve and how many times have u read how bad it is to run fuel threw a gm blower with a wet kit well what do u think is going to eventually happen when the inside of the blower is lined in a high detergent synthetic oil that he is most likely running . its the blind leading the blind go understand how something works before u give advise on how to improve it
YOU WANT VACUUM ON THE CRANKCASE!!!!
When you get blowby it pressurizes the crankcase and without a vacuum it will build up and create pressure on the underside of the pistons decreasing gas mileage and ring life. The system is not necessarily designed to suck oil into the intake tract but it does happen. Thats why 2.4s have a AIR TO OIL seperator. If your at all concerned put a catch can in. But for your cars sake please do not listen to what LEVI thinks he knows is right.
the only way the pressure will build is if u plug it off. and if the 3/4'' line that come off the oil separator can't flow enough with a breather on the end than u have much bigger problems to worry about. i have ran this set up on my own car from day one and i have even put my hand on the filter during dyno pulls to see how much it blows when it had a 75shot and now a turbo not counting every race car i have set up that way at my shop from 400hp v-tecs to 800hp big blocks please feel free to post any pictures of any race oriented vehicle that is sucking that crap into the motor good luck do what u feel comfortable doing but I'm not going to argue with a 16 year old kid about something i know is right
the rings can contain an explosion so a fart on the other side is nothing to worry about i posted a picture of my car (i hope) u can see the kn breather sticking up right in front of the fpr this is right off the oil separator i never needed a can
^^^^^^^^^Agree
Thats Him Officer The WICKED One.
